Abstract: A monofocal contact lens (10) having an anterior surface (34) and a posterior surface is provided. The monofocal contact lens (10) includes an optic zone (30) providing monofocal optical properties located substantially in the center of the contact lens (10) and a peripheral zone (32) surrounding the optic zone (30). The peripheral zone (32) includes a three-dimensional pattern (35) placed on the posterior surface of the contact lens (10). The three-dimensional pattern (35) includes portions not in contact with the surface (33) of the eye (31).

Abstract: L'invention concerne un élément optique diffractif (11) et un procédé pour produire un tel élément. L'élément optique (11) comprend une base (13) et au moins des première et seconde zones de phase (14), la première zone de phase (14) comprenant une première multitude de gradins (22) et la seconde zone de phase comprenant une seconde multitude de gradins (22), la distance entre le ième gradin de ladite première zone de phase (14) et la base (13) étanat différente de la distance entre un ième gradin de ladite seconde zone de phase (14) et la base (13), pour au moins une valeur de i. Le procédé de production de l'élément optique diffractif (11) de la présente invention comprend les étapes de définition d'un ensemble de masques pour la création de zones de phase à gradins (14) de sorte qu'au moins l'un des masques cache entièrement au moins un gradin (22) d'au moins une zone de phase (14) pour qu'au moins un gradin (22) d'au moins une zone de phase (14) ne soit pas attaqué.

Abstract: A progressive multifocal lens for eyeglasses formed along a principle meridian curve, with a farsighted vision zone (1) having an optical power corresponding to that required for viewing distant objects, a nearsighted vision zone (3) having an optical power corresponding to that required for viewing near objects, and an intermediate vision zone (2) between and progressively connecting the farsighted vision zone and the nearsighted vision zone, includes a transparent, non-rotationally-symmetrical, microrelief structure in one or more of these vision zones.

Abstract: A diffractive optical element (11) and a method to produce same is disclosed. The optical element (11) comprises a base (13) and at least first and second phase zones (14) wherein the first phase zone (14) comprises a first multiplicity of steps (22) and the second phase zone comprises a second multiplicity of steps (22) and wherein a distance from an ith step of said first phase zone (14) to said base (13) is different than a distance of an ith step of said second phase (14) zone to said base (13), for at least one value of i. The method to produce the diffractive optical element (11) of the present invention includes the step of defining a collection of masks for creating stepped phase zones (14) wherein at least one of the collection of masks completely masks out at least one step (22) of at least one phase zone (14) such that the at least one step (22) of the at least one phase zone (14) will not be etched.
